Music to a worker’s ears
Tune in to music, a favorite sports team, or talk radio on QuieTunes AM/FM model 660 earmuff. The electronics are separated from hearing protection cavities to avoid problems from moisture and sweat that affect the life span of electronics. Uses two AA alkaline batteries (included), replaceable through an external battery compartment. A fresh set of batteries provides about 150 hrs. of operation. If worker forgets to turn off the radio, an automatic 4-hour shutoff prevents a dead unit. A gain limiter keeps speaker sound to a safe level.
